All I could recommend there is to open the archive that you've downloaded, and remove the same files that it installs - that's the only way to be sure.Yes it does show there. So I ended up getting it to show up on the list after rebooting, but still failing to launch. I've tried both a clean install of Bahrain 2020 without extension, and with the extension installed afterward. I'm realizing I'm having a lot of issues with several of the tracks. I could try a full reinstall of the tracks again - is there anything I need to do to ensure the extensions also get uninstalled when I try to wipe the tracks?
